I'm a Newbie Here ad hope to be very active, You sure gave me a lot of knowledge on the Frame and I wanted to Thank You And Your Thought For The Day It's going Keep Me Going for the rest of the Day . Thanks Again /Mike

You can do caped straight joints or mite joints . There's pros and cons to each.I've used both on mine.look back at the start of my build thread.im not claiming to be an expert, I have alot of welding experience but it was 25 to 30 years ago.do what's comfortable to you and if you've got a cut off saw it makes life easier

Caped joins mean more welding and linishing to finish but allow for a greater margin of error if using a mig.The other thing is as I did you can weld you frame up based on your wheel base with the side rails and then cut back the front and back rails to suit afterwards

It is a bit harder to get mitered joints to square up and fit nice when welding. The only reason I can see to do it that way is if you wanted to run wires inside and needed to turn the corner with them. However, I would never run wires loose inside of a trailer frame because they would not be secure, could chafe, and would be much more difficult to service or troubleshoot.

My writing style is a bit tedious, but there is extensive coverage of how I built the trailer for TPCE in the beginning of my build thread (link below). Might be a little more detailed than needed, but you can take from it what you want.

You guys just answered my questions thanks(I will be Arc welding, think you muricans call it stick welding)

I get my steel next week so I will post some pics of what I planfor nowthe exterior frame will be 40x40mm boxthe cross beams will be 40x40 angle ironThe drawbar will be 75x50axle will be 50x50 on 600kg leaf springs

Frame Tutorial update: Rich and I had put this together years ago. Since Rich has passed, the account that hosted that work is suspended and I would imagine gone for good. I have none of the work. If someone would like to step forward and put something together on the topic that would be great and I"m sure that many on the forum could learn a lot from it. Doug
